DETAILED DESCRIPTION Overview

A hinge mechanism with multiple preset positions is described. In atleast some implementations, the hinge mechanism enables a supportcomponent to be adjustably attached to an apparatus, such as a computingdevice. For example, the hinge mechanism can be employed to rotatablyattach a kickstand to a mobile computing device. The kickstand can berotated via the hinge mechanism to various positions to provide supportfor different orientations of the computing device. For example, thekickstand can be positioned to support the computing device in a typingorientation such that input can be provided via an associated inputdevice. As another example, the kickstand can be positioned to enableviewing and/or interaction with the computing device, such as in aportrait viewing orientation.

In at least some implementations, a hinge mechanism utilizes presethinge positions that enable a kickstand to be placed at different presetpositions. Further, the hinge mechanism includes a center of rotationthat is external to the hinge mechanism. Thus, the kickstand can conformto a contour of the computing device when in a closed position, andmaintain a minimal external profile when moving between the differentpreset positions. According to various implementations, the hingemechanism includes an emergency escape position that enables thekickstand to be rotated beyond normal operating positions withoutdamaging the kickstand or detaching the kickstand from an associateddevice.

In at least some implementations, the hinge mechanism discussed hereinis configured such that an attached support component tends to “snap”into various preset positions. Generally, snapping refers to movement ofthe hinge mechanism in response to force generated internally to thehinge mechanism, e.g., via a hinge spring and/or other component thatprovides elastic force for the hinge mechanism. In at least someimplementations, snapping occurs when a user releases a supportcomponent, e.g., independent of user-applied force to the supportcomponent. For instance, torque forces that apply during movement of thehinge mechanism are such that the hinge mechanism typically does notrest at positions outside of the preset positions unless held there by auser. Thus, torque forces at work during movement of an attached supportcomponent provide a form of tactile feedback that indicates to a userwhether the support component is positioned in a normal operatingposition, e.g., at a preset position for the hinge mechanism. Variousattributes and components of example hinge mechanisms are presented indetail below.

In the following discussion, an example environment is first describedthat may employ the techniques described herein. Embodiments discussedherein are not limited to the example environment, and the exampleenvironment is not limited to embodiments discussed herein. Next,example device orientations are discussed in accordance with one or moreembodiments. Following this, an example kickstand is described inaccordance with one or more embodiments. Next, example hinges forkickstand attachment are discussed in accordance with one or moreembodiments. Following this, a section entitled “Hinge ResponsivenessProfile” discusses an example torque profile for hinge movement inaccordance with one or more embodiments. Finally, an example system anddevice are discussed that may implement various techniques describedherein.

Example Environment

FIG. 1 is an illustration of an environment 100 in an exampleimplementation that is operable to employ the techniques describedherein. The illustrated environment 100 includes an example of acomputing device 102 that is physically and communicatively coupled toan input device 104 via a flexible hinge 106. The computing device 102may be configured in a variety of ways. For example, the computingdevice 102 may be configured for mobile use, such as a mobile phone, atablet computer as illustrated, a wearable device, and so on.

While embodiments presented herein are discussed in the context of atablet device, it is to be appreciated that various other types and formfactors of devices may be utilized in accordance with the claimedembodiments. Thus, the computing device 102 may range from full resourcedevices with substantial memory and processor resources, to alow-resource device with limited memory and/or processing resources. Anexample implementation of the computing device 102 is discussed belowwith reference to FIG. 36.

The computing device 102 is illustrated as including an input/outputmodule 108, which is representative of functionality relating toprocessing of inputs and rendering outputs of the computing device 102.A variety of different inputs may be processed by the input/outputmodule 108, such as inputs relating to functions that correspond to keysof the input device 104, keys of a virtual keyboard displayed by thedisplay device 110 to identify touch gestures and cause operations to beperformed that correspond to the touch gestures that may be recognizedthrough the input device 104 and/or touchscreen functionality of thedisplay device 110, and so forth. Thus, the input/output module 108 maysupport a variety of different input techniques by recognizing andleveraging a division between types of inputs including key presses,touch gestures, touchless gestures recognized via a camera functionalityof the computing device 102, and so on.

In the illustrated example, the input device 104 is configured as havingan input portion that includes a keyboard having a QWERTY arrangement ofkeys and track pad although other arrangements of keys are alsocontemplated. Further, other non-conventional configurations are alsocontemplated, such as a game controller, configuration to mimic amusical instrument, and so forth. Thus, the input device 104 and keysincorporated by the input device 104 may assume a variety of differentconfigurations to support a variety of different functionality.

As previously described, the input device 104 is physically andcommunicatively coupled to the computing device 102 in this examplethrough use of a flexible hinge 106. The flexible hinge 106 is flexiblein that rotational movement supported by the hinge is achieved throughflexing (e.g., bending) of the material forming the hinge as opposed tomechanical rotation as supported by a pin, although that embodiment isalso contemplated. Further, this flexible rotation may be configured tosupport movement in one or more directions (e.g., vertically in thefigure) yet restrict movement in other directions, such as lateralmovement of the input device 104 in relation to the computing device102. This may be used to support consistent alignment of the inputdevice 104 in relation to the computing device 102, such as to alignsensors used to change power states, application states, and so on.

Example Device Orientations

According to various embodiments, a variety of different orientations ofthe computing device 102 are supported. For example, rotational movementmay be supported by the flexible hinge 106 such that the input device104 may be placed against the display device 110 of the computing device102 and thereby act as a cover as shown in the example orientation 200of FIG. 2. Thus, the input device 104 may act to protect the displaydevice 110 of the computing device 102 from harm.

As shown in the example orientation 300 of FIG. 3, a typing arrangementmay be supported. In this orientation, the input device 104 is laid flatagainst a surface and the computing device 102 is disposed at an angleto permit viewing of the display device 110, e.g., such as through useof a kickstand 302 disposed on a rear surface of the computing device102.

Naturally, a variety of other orientations other than those expresslyillustrated and discussed herein are also supported.

Kickstand

The described kickstand can be employed as a support component to enablea variety of different orientations for the computing device 102. Forinstance, consider the following implementations of a kickstand inaccordance with various embodiments.

FIG. 4 illustrates an orientation 400, and includes the kickstand 302 ina closed position. In the closed position, the kickstand 302 forms aportion of a rear surface 402 of the computing device 102 such that thekickstand 302 conforms to a surface contour of the computing device 102.For instance, when the kickstand 302 is in the closed position, thekickstand 302 integrates into the computing device 102 and does notprotrude from a plane formed by the rear surface 402.

FIG. 5 illustrates that the kickstand 302 can be rotated away from therear surface 402 of the computing device 102 to a position 500. Forinstance, the kickstand 302 can be rotatably attached to the computingdevice 102 along a seam 502 via a hinge mechanism. Examples of such ahinge mechanism are detailed below.

In at least some implementations, the position 500 corresponds to apreset position for the kickstand 302. For instance, when a user appliespressure to the kickstand 302 away from the rear surface 402, thekickstand 302 can snap into the position 500. As detailed below, a hingemechanism employed to attach the kickstand 302 to the computing device102 can utilize spring pressure and detent settings to provide presetopen positions for the kickstand 302. In this example, the position 500is associated with an angle 504 between the rear surface of thecomputing device 102 and the kickstand 302. For instance, the angle 504can range from 45 degrees (45°) to 55 degrees (55°). The angle 504, forexample, is approximately 48°, +/−3°. Any suitable angle and/or range ofangles may be employed, however.

According to various implementations, the position 500 places the frontsurface of the display device 110 at an angle 506 relative to a verticalline 508. The vertical line 508, for instance, is normal (i.e., 90°) toa surface 510 on which the computing device 102 and the kickstand 302are disposed. In this particular example, the angle 506 is approximately24°, +/−3°. The angle 506, for instance, is one-half of the angle 504.

As illustrated, the input device 104 can be rotated away from thecomputing device 102 and supported by the kickstand 302. The position500, for instance, enables the display device 110 to be viewed and inputto be provided to the computing device 102 via the input device 104.Alternatively or additionally, the position 500 enables a user tointeract with a touchscreen of the computing device 102.

FIG. 6 illustrates that the kickstand 302 can be rotated away from therear surface 402 of the computing device 102 to a position 600. Forinstance, the kickstand 302 can be rotated further past the position 500to the position 600.

In at least some implementations, the position 600 corresponds to afurther preset position for the kickstand 302. For example, when a userapplies pressure to the kickstand 302 away from the rear surface 402(e.g., past the position 500), the kickstand 302 can snap into theposition 600. In this example, the position 600 is associated with anangle 602 between the rear surface of the computing device 102 and thekickstand 302. For instance, the angle 602 can range from 80 degrees(80°) to 85 degrees (90°). The angle 602, for example, is approximately84°, +/−4°. Any suitable angle and/or range of angles may be employed,however. Further, the seam 502 can be maintained (e.g., the width of theseam) during rotation to the position 600.

With the kickstand 302 in the position 600, the computing device 102supports a variety of different usage scenarios. For instance, considerthe following two example scenarios.

FIG. 7a illustrates a side view of the computing device 102 in anorientation 700 and with the kickstand 302 positioned in the position600. In the position 700, the computing device is reclined in comparisonto previously-discussed orientations, such as the orientation 300discussed above with reference to FIG. 3. As illustrated, theorientation 700 presents the display device 110 at a more open anglethat supports different usage scenarios. For instance, the orientation700 supports use of the computing device 102 in a user's lap, such asduring air travel. A variety of other usage scenarios are supported bythe orientation 700, such as for tall users that may have a higherviewing angle, use on a low surface (e.g., a coffee table), and soforth.

According to various implementations, the orientation 700 places thefront surface of the display device 110 at an angle 702 relative to avertical line 704. The vertical line 704, for instance, is normal (i.e.,90°) to a surface 706 on which the computing device 102 and thekickstand 302 are disposed. In this particular example, the angle 702 isapproximately 42°, +/−5°. The angle 702, for instance, is one-half ofthe angle 602.

With the kickstand 302 in the position 600, the computing device 102 canalso be rotated sideways (e.g., to a portrait viewing position) andsupported via the kickstand 302. For instance, consider an orientation708 illustrated in FIG. 7 b.

FIG. 7b illustrates a rear view of the computing device 102 in theorientation 708, showing that the computing device 102 is rotated to aportrait viewing position, such as 90 degrees (90°) to the orientationillustrated in FIG. 1. Further, the kickstand 302 is positioned in theposition 600 such that the computing device 102 reclines back and issupported by the kickstand 302 on a surface 710. According to variousimplementations, placing the computing device 102 in the orientation 708can cause a view orientation of the display device 110 to be rotated toa portrait view.

In FIG. 7b , the computing device 102 is illustrated without the inputdevice 104. Thus, in at least some embodiments the input device 104 canbe separated from the computing device 102 such that the computingdevice 102 has functionality independent of the input device 104. Forexample, the flexible hinge 106 can employ a magnetic attachmentmechanism that holds the input device 104 to the computing device 102via magnetic force. Thus, a user can grasp the computing device 102 andthe input device 104, and can pull the two apart by overcoming themagnetic attraction between them.

When separate from the input device 104, the computing device 102 canprovide various functionality. For example, a user can view content viathe computing device 102, such as movies and/or streaming content.Further, a user can interact with touch screen functionality of thedisplay device 110.

Thus, placing the kickstand 302 in the position 600 can enable a user toplace the computing device in a landscape and/or portrait orientation,and to view and/or interact with the computing device in suchorientations.

FIG. 8 illustrates that the kickstand 302 can be rotated away from therear surface 402 of the computing device 102 to a position 800. Forinstance, the kickstand 302 can be rotated further past the position 600to the position 800.

In at least some implementations, the position 800 corresponds to afurther preset position for the kickstand 302. For example, when a userapplies pressure to the kickstand 302 away from the rear surface 402(e.g., past the position 600), the kickstand 302 can snap into theposition 800. In this example, the position 800 is associated with anangle 802 between the rear surface of the computing device 102 and thekickstand 302. For instance, the angle 802 can range from 113 degrees(113°) to 123 degrees (123°). The angle 602, for example, isapproximately 118, +/−5°. Any suitable angle and/or range of angles maybe employed, however.

According to various implementations, the position 800 places the frontsurface of the display device 110 at an angle 804 relative to a verticalline 806. The vertical line 806, for instance, is normal (i.e., 90°) toa surface 808 on which the computing device 102 and the kickstand 302are disposed. In this particular example, the angle 804 is approximately59°, +/−5°. The angle 804, for instance, is one-half of the angle 802.

FIG. 9 illustrates a view of an inner surface 900 of the kickstand 302in accordance with one or more embodiments. In this example, thekickstand 302 is illustrated in the context of an outline of a chassisof the computing device 102. The inner surface 900 includes hinge mounts902 a, 902 b, which function as mounting points for hinge mechanismsthat are employed to attach the kickstand 302 to the computing device102. Examples of such hinge mechanisms are discussed below.

Hinges for Component Attachment

A variety of different hinge mechanisms can be employed for attachingvarious components in accordance with various embodiments. Some examplehinge mechanisms and hinge arrangements are discussed below.

FIG. 10 illustrates an exploded rear view 1000 of a chassis of thecomputing device 102 and the kickstand 302. Included in the rear view1000 are hinges 1002 a and 1002 b, which are employed to attach thekickstand 302 to the computing device 102. The hinges 1002 a, 1002 b areconfigured to be installed internally in the computing device 102, suchas via a suitable attachment method and/or device.

The kickstand 302 can be attached to a pivoting portion of the hinges1002 a, 1002 b via the hinge mounts 902 a, 902 b, discussed above withreference to FIG. 9. Thus, attachment to the hinges 1002 a, 1002 benables the kickstand 302 to pivot between various positions withreference to the computing device 102.

FIG. 11 illustrates components of an example hinge 1100 in accordancewith one or more embodiments. The hinge 1100, for instance, canrepresent an implementation of the hinges 1002 a, 1002 b discussedabove. This is not intended to be limiting, however, and the hinge 1100can be employed as a hinge mechanism for a variety of differentcomponents and in a variety of different attachment scenarios. The hinge1100 and its various components can be formed using any suitablematerial and/or combination of materials, such as metals, plastics,polymers, alloys, and so forth.

Components of the hinge 1100 include a hinge frame 1102 in which variousother components of the hinge 1100 can be disposed. For example, thehinge frame 1102 can be mounted to and/or within a device (e.g., thecomputing device 102) and function as a support structure for othercomponents of the hinge 1100.

Further included are a cam 1104, a cam follower 1106, a support plate1108 a, and a support plate 1108 b. As detailed elsewhere herein,interaction between the cam 1104 and the cam follower 1106 within thehinge 1100 provides a particular responsiveness profile during usermanipulation of a component attached to the hinge 1100, e.g., thekickstand 302. Further, the support plates 1108 a, 1108 b providelateral support for the hinge 1100 in various open positions and enablethe hinge 1100 to be positioned in various open positions. For purposeof discussion herein, the support plates 1108 a, 1108 b may be referredto as a support plate 1108.

The hinge 1100 also includes a hinge spring 1110, which applies pressureto the cam follower 1106 when the various components are placed in theirrespective positions within the hinge frame 1102. Further detailsconcerning components and functionality of the hinge 1100 are nowdiscussed.

FIG. 12 illustrates a detail of portions of the hinge frame 1102. Theview of the hinge frame 1102 presented in FIG. 12 is rotated 180 degreesrelative to the view illustrated in FIG. 11. The hinge frame 1102includes hinge mounts 1200 a and 1200 b by which the hinge frame 1102,and thus the hinge 1100, can be mounted to an apparatus. For instance,the hinge mounts 1200 a, 1200 b represent apertures through which afastening mechanism such as a screw or bolt can be positioned andfastened into an apparatus, such as the computing device 102.

The hinge frame 1102 further includes a cam follower mount 1202 intowhich the cam follower 1106 can be mounted. While not expresslyillustrated here, the cam follower mount 1202 includes a similar portionon the opposite inside surface of the hinge frame 1102, thus forming acradle into which a mounting portion of the cam follower 1106 can beattached.

Plate guides 1204 a, 1204 b represent raised portions on the insidesurface of the hinge frame 1102 which are employed for mounting thesupport plates 1108 a, 1108 b into the hinge frame 1102. For instance,the plate guides 1204 a, 1204 b represent raised portions (e.g., curvedrails) that are mirror images of one another on opposite inside surfacesof the hinge frame 1102. Generally, the support plates 1108 a, 1108 bengage with the plate guides 1204 a, 1204 b to hold the support plates1108 a, 1108 b within the hinge frame 1102. During movement of acomponent attached to the hinge 1100 between one or more open positions,the plate guides 1204 a, 1204 b cause rotational movement of the supportplates 1108 a, 1108 b. As further illustrated herein, rotationalmovement of the support plates 1108 a, 1108 b enables an attachedcomponent to be positioned in various different positions.

The hinge frame 1102 further includes a spring mount 1206, whichrepresents a surface onto which the hinge spring 1110 is placed. Asfurther detailed elsewhere herein, placement of the hinge spring 1110onto the spring mount 1206 enables the hinge spring 1110 to exertpressure upon the cam follower 1106. Spring pressure on the cam follower1106 holds the cam follower against the cam 1104 and thus enables thecam 1104 to be held in various preset positions.

FIG. 13 illustrates a detail of portions of the support plates 1108 a,1108 b. Illustrated as part of an inner support surface 1300 of thesupport plate 1108 a is a cam guide 1302. Although not illustrated here,the support plate 1108 b similarly includes a respective cam guide 1302on its inner surface. Generally, the cam guides 1302 protrude from thesurfaces of the respective support plates 1108 a, 1108 b and engage withthe cam 1104 to moveably attach the cam 1104 to the hinge 1100. Duringmovement of a component attached to the cam 1104, the cam guides 1302enable rotational movement of the cam 1104 relative to the hinge frame1102. As further illustrated herein, rotational movement of the cam 1104enables an attached component to be placed in various positions.

An outer surface 1304 of the support plate 1108 b includes a supportchannel 1306 that engages with the plate guide 1204 b of the hinge frame1102, introduced above. For instance, the dimensions of the supportchannel 1306 are such that the plate guide 1204 b fits within thesupport channel 1306 when the support plate 1108 b is mounted within thehinge frame 1102. During movement of the support plate 1108 b relativeto the hinge frame 1102, the support channel 1306 slides relative to theplate guide 1204 b to enable rotational movement of the support plate1108 b relative to the hinge frame 1102. Although not illustrated here,an outer surface of the support plate 1108 a similarly includes arespective plate channel 1306 that engages with the plate guide 1204 aof the hinge frame 1102. Further features of the support plates 1108 arediscussed below.

FIG. 14 illustrates example details of the cam 1104. The cam 1104includes an inner cam surface 1400 and outer cam surfaces 1402 a, 1402b. As illustrated, the inner cam surface 1400 is recessed in a channelalong an inside portion of the cam 1104. The inner cam surface 1400, forinstance, is positioned along center lengthwise axis of the cam 1104.

The outer cam surfaces 1402 a, 1402 b are positioned on either side ofthe inner cam surface 1400 and protrude above the inner cam surface1400. According to various implementations, the outer cam surfaces 1402a, 1402 b are mirror images of one another, and may be referred toherein as an outer cam surface 1402. As further detailed below, theinner cam surface 1400 and the outer cam surfaces 1402 a, 1402 b havespecific surface profiles that interact with the cam follower 1106 toprovide a particular response profile during movement of an attachedcomponent.

The cam 1104 further includes a cam channel 1404 and a componentmounting portion 1406. The cam channel 1404 is formed such that when thecam 1104 is mounted within the hinge frame 1102 relative to the supportplates 1108, the cam channel 1404 engages with the cam guide 1302 of thesupport plate 1108. Although not illustrated here, the opposite side ofthe cam 1104 includes a respective cam channel 1404. The dimensions ofthe cam guide 1302 of the support plate 1108, for instance, are suchthat the cam guide 1302 fits within the cam channel 1404. Duringmovement of the cam 1104 relative to the hinge frame 1102, the camchannel 1404 slides relative to the cam guide 1302 to enable rotationalmovement of the cam 1104 relative to the support plates 1108 a, 1108 b.

The component mounting surface 1406 is representative of a portion ofthe cam 1104 to which a component (e.g., the kickstand 302) can bemounted. For instance, the component mounting surface 1406 includessurface attributes that engage and/or interlock with a component tostabilize the component relative to the cam 1104. Alternatively oradditionally, the component mounting surface 1406 may include one ormore apertures through which a fastening device such as a screw or boltmay be placed to fasten the hinge to a component.

FIG. 15 illustrates a detail of a top surface 1500 of the cam follower1106. The top surface 1500 includes a follower pivot 1502 which isformed to engage within the cam follower mount 1202 (introduced above)of the hinge frame 1102. For instance, the follower pivot 1502 isfashioned such that the follower pivot slidably rotates within the camfollower mount 1202 during movement of various components of the hinge1100.

The top surface 1500 of the cam follower 1106 further includes a springplatform 1504 which is configured to engage with the hinge spring 1110.For example, spring tension from the hinge spring 1110 against thespring platform 1504 holds the cam follower 1106 against the cam 1104.Thus, spring tension against the cam follower 1106 results in a reactionat the cam 1104 that provides a torque response at the cam 1104. Asdiscussed herein, the torque response results at least in part from theshape of the cam 1104 and the cam follower 1106, and the interactionbetween their respective surfaces.

For instance, depending on the angular position of the cam 1104 and thedirection of motion, movement of the cam 1104 may be either resisted(e.g., opposed) or driven. This interaction between the differentelements of the hinge 1100 provides for a “snappy” response of anattached component, e.g., the kickstand 302.

FIG. 16 illustrates a detail of a bottom surface 1600 of the camfollower 1106. The bottom surface 1600 includes lower portions of thefollower pivot 1502 and the spring platform 1504, introduced above.

The bottom surface 1600 further includes an inner follower surface 1602and outer follower surfaces 1604 a, 1604 b. For purpose of discussion,the outer follower surfaces 1604 a, 1604 b may be referred to as anouter follower surface 1604. The inner follower surface 1602 protrudesfrom the bottom surface 1600 relative to the outer follower surfaces1604 a, 1604 b. As detailed elsewhere herein, the inner follower surface1602 and the outer follower surfaces 1604 a, 1604 b interact withsurfaces of the cam 1104 to provide a particular torque response for acomponent attached to the hinge 1100.

FIG. 17 illustrates locations of vertical cross-sections of the hinge1100 which will be used to describe function and attributes of the hinge1100 in subsequent figures. Included are a first cross-section 1700, asecond cross-section 1702, and a third cross-section 1704. Generally,these cross-sections define respective planes through the hinge 1100.Reference to these different cross-sections will be made in thesubsequent discussion. Further illustrated are the hinge frame 1102, thecam 1104, the support plates 1108 a, 1108 b, and the bottom portion ofthe spring platform 1504 of the cam follower 1106.

FIG. 18 illustrates the computing device 102 with the kickstand 302 in aposition 1800. In at least some embodiments, the position 1800corresponds to a closed position for the kickstand 302, such asdiscussed above with reference to FIG. 4. Further illustrated is apartial side section view 1802 of the computing device 102, includingthe kickstand 302 attached to the cam 1104 of the hinge 1100 in a closedposition. The section view 1802, for instance, corresponds to thecross-section 1704 illustrated above. In the partial side view 1802 andsubsequent views presented in subsequent figures, the hinge 1100 isillustrated with the kickstand 302 and the portions of the rear surface402 of the computing device 102, but without other portions of thecomputing device 102.

In the section view 1802, the cam 1104 is sectioned lengthwise down thecenter, and thus the illustrated section of the cam 1104 illustrates asurface profile of the inner cam surface 1400, introduced above. The camfollower 1106 is also sectioned lengthwise down the center, and thus theillustrated section of the cam follower 1106 illustrates a surfaceprofile of the inner follower surface 1602.

In the position 1800, force applied by the hinge spring 1110 holds thecam follower 1106 against the cam 1104. Further, the interface betweenthe cam follower 1106 and the cam 1104 is such that movement of thekickstand 302 is resisted. For instance, the inner follower surface 1602presses against an inner cam contact 1804, and the hinge spring 1110resists rotational movement of the cam follower 1106 on the followerpivot 1502. Thus, absent force applied by a user to the kickstand 302,pressure from the cam follower 1106 against the cam 1104 holds thekickstand 302 in a closed position against the computing device 102.

FIG. 19 illustrates the computing device 102 with the kickstand 302 inthe position 1800, introduced above. Further illustrated is a partialside section view 1902 of the computing device 102, including thekickstand 302 attached to the cam 1104 of the hinge 1100 in a closedposition. The section view 1902, for instance, corresponds to thecross-section 1702 illustrated above.

Illustrated as part of the section view 1902 are the outer followersurface 1604 of the cam follower 1106, and the outer cam surface 1402 ofthe cam 1104. As illustrated, in the position 1800 (e.g., a closedposition), the outer follower surface 1604 does not contact the outercam surface 1402.

FIG. 20 illustrates the kickstand 302 in a position 2000. In at leastsome embodiments, the position 2000 corresponds to a first preset openposition for the kickstand 302, such as the position 500 illustratedwith reference to FIG. 5. Further illustrated is a partial side sectionview 2002 of the computing device 102, including the kickstand 302attached to the cam 1104 of the hinge 1100 in a first open position. Thesection view 2002, for instance, corresponds to the cross-section 1704illustrated in FIG. 17.

According to various implementations, movement of the kickstand 302 fromthe position 1800 to the position 2000 is initially resisted by pressurefrom the inner follower surface 1602 against the inner cam contact 1804.However, when movement of the inner cam contact 1804 proceeds past aninner follower point 2004, pressure from the inner follower surface 1602against the inner cam contact 1804 drives the cam 1104 to the position2000. For instance, if a user begins opening the kickstand 302 from theposition 1800 but releases the kickstand 302 before the inner camcontact 1804 proceeds past the inner follower point 2004, the cam 1104and thus the kickstand 302 will snap back into a closed position, e.g.,the position 1800.

However, if the user manipulates the kickstand 302 such that the innercam contact 1804 proceeds past the inner follower point 2004, pressurefrom the cam follower 1106 against the cam 1104 drives the cam 1104 intothe position 2000, e.g., a first open position. For instance, if theuser releases the kickstand 302 after the inner cam contact 1804proceeds past the inner follower point 2004, the cam 1104 (and thus thekickstand 302) will snap into the position 2000.

According to various implementations, the hinge 1100 has a center ofrotation 2006 this is external to the hinge itself. For instance, thecenter of rotation 2006 substantially coincides with the seam 502between the kickstand 302 and stationary portions of the rear surface402 of the computing device 102. Further, in at least someimplementations, the center of rotation 2006 is consistent (e.g., doesnot change) when the hinge 1100 is repositioned among the various presetopen positions discussed herein. This enables the kickstand 302 tomaintain a consistent rotational profile and causes a width of the seam502 to remain substantially consistent (e.g., within +/−0.050millimeters) during rotation of the kickstand 302 among the differentpreset positions discussed herein.

FIG. 21 illustrates the computing device 102 with the kickstand 302 inthe position 2000, introduced above. Further illustrated is a partialside section view 2100 of the computing device 102, including thekickstand 302 attached to the cam 1104 of the hinge 1100 in an openposition. The section view 2100, for instance, corresponds to thecross-section 1702 illustrated above. According to variousimplementations, the section view 2002 (above) and the section view 2100illustrate different cross-sections of the same position for the hinge1100, e.g., the position 2000.

Illustrated in the section view 2100 is the outer cam surface 1402 ofthe cam 1104 and the outer follower surface 1604 of the cam follower1106. Further illustrated is that a first cam catch 2102 on the outercam surface 1402 engages with a first follower catch 2104 on the outerfollower surface 1604. Generally, the first cam catch 2102 and the firstfollower catch 2104 represent surface features on the outer cam surface1402 and the outer follower surface 1604, respectively.

According to various implementations, engagement of the first cam catch2102 with the first follower catch 2104 enables the kickstand 302 topersist in the position 2000. For instance, spring pressure from thehinge spring 1110 holds the first cam catch 2102 against the firstfollower catch 2104. In at least some implementations, absent externalforce directly and/or indirectly applied to the kickstand 302, the firstcam catch 2102 will not disengage from the first follower catch 2104.

For example, the hinge 1100 is constructed such that unless a specifiedthreshold force is applied to the kickstand 302, the hinge 1100 will notdisengage from the position 2000. In at least some implementations,exceeding a threshold closing force against the kickstand 302 in onedirection closes the kickstand, and exceeding a threshold opening forceagainst the kickstand 302 in another direction opens the kickstand 302further past the position 2000.

According to one or more implementations, contact between the cam 1104and the cam follower 1106 occurs between the inner cam surface 1400 andthe inner follower surface 1602 when the hinge 1100 is in a positionfrom the closed position 1800 and up to the open position 2000. Forinstance, for a kickstand angle range of 0 degrees (e.g., position 1800)up to the position 2000, the outer cam surface 1402 does not contact theouter follower surface 1604.

However, starting with the position 2000 and continuing to further openpositions such as those discussed below, contact between the cam 1104and the cam follower 1106 transitions to the outer cam surface 1402 andthe outer follower surface 1604. In these further open positions, forexample, the inner cam surface 1400 is positioned away from and does notcontact the inner follower surface 1602. Thus, as detailed herein,responsiveness of the hinge 1100 between at least some positions changesbased on surface profiles of the different cam and cam followersurfaces, and also based on which surfaces are engaged at a particularposition.

While the discussion herein is presented with reference to a particularouter follower surface 1604 and a particular outer cam surface 1402, itis to be appreciated that according to various implementations, similarfeatures and interactions apply to the other outer follower surface andouter cam surface.

FIG. 22 illustrates a partial rear view 2200 of the computing device 102with the kickstand 302 in the position 2000. The rear view 2200illustrates that in at least some implementations, the support plates1108 a, 1108 b remain recessed within the hinge frame 1102 and the cam1104 rotates out of the hinge frame 1102 when the kickstand is moved tothe position 2000. This is not intended to be limiting, however, and thesupport plates 1108 may move in response to movement of the cam 1104,e.g., due to contact between the cam guide 1302 and the cam channel1404.

FIG. 23 illustrates the kickstand 302 in a position 2300. In at leastsome embodiments, the position 2300 corresponds to a second preset openposition for the kickstand 302, such as the position 600 illustratedwith reference to FIG. 6. The kickstand 302 is placed in the position2300, for instance, responsive to a user further opening the kickstand302 past the position 2000 introduced above. Further illustrated is apartial side section view 2302 of the computing device 102, includingthe kickstand 302 attached to the cam 1104 of the hinge 1100 in a firstopen position. The section view 2302, for instance, corresponds to thecross-section 1702 illustrated above.

According to various implementations, movement of the kickstand 302 fromthe position 2000 to the position 2300 is initially resisted by pressurefrom the first follower catch 2104 against the first cam catch 2102.However, when movement of the first cam catch 2102 proceeds past anouter follower point 2304, pressure from the outer follower surface 1604against the first cam catch 2102 drives the cam 1104 to the position2300. In the position 2300, the first cam catch 2102 engages with asecond follower catch 2306.

For instance, if a user begins opening the kickstand 302 further pastthe position 2000 but releases the kickstand 302 before the first camcatch 2102 proceeds past the outer follower point 2304, the cam 1104 andthus the kickstand 302 will snap back into the position 2000. However,when movement of the kickstand 302 proceeds past the position 2000 suchthat the first cam catch 2102 proceeds past the outer follower point2304, the cam 1104 and thus the kickstand 302 will snap into theposition 2300. For example, consider that a user releases the kickstand302 when the first cam catch is between the outer follower point 2304and the second follower catch 2306. In such a case, the sloped profileof the outer follower surface 1604 is such that pressure from outer camfollower 1604 (provided by the hinge spring 1110) drives the cam 1104and thus the kickstand 302 into the position 2300 independent of anexternally applied (e.g., user-applied) force.

According to various implementations, engagement of the first cam catch2102 with the second follower catch 2306 enables the kickstand 302 topersist in the position 2300. For instance, spring pressure from thehinge spring 1110 holds the second follower catch 2306 against the firstcam catch 2101 and thus prevents the cam 1104 and thus the kickstand 302from disengaging from the position 2300 unless sufficient external forceis applied. Thus, absent force directly and/or indirectly applied to thekickstand 302, the first cam catch 2102 will not disengage from thesecond follower catch 2306.

For example, the hinge 1100 is constructed such that unless a specifiedthreshold force is applied to the kickstand 302, the hinge 1100 will notdisengage from the position 2300. In at least some implementations,exceeding a threshold closing force against the kickstand 302 causes thekickstand 302 to transition back to the position 2000, and exceeding athreshold opening force against the kickstand 302 opens the kickstand302 further past the position 2300.

Notice that in the position 2300, a second cam catch 2308 engages with acam stop 2310 of the support plate 1108. As further detailed below,engagement of the second cam catch 2308 with the cam stop 2310 enablesmovement of the support plate 1108 to support further open positions forthe kickstand 302.

FIG. 24 illustrates the kickstand 302 in the position 2300, introducedabove. Further illustrated is a partial side section view 2400 of thecomputing device 102, including the kickstand 302 attached to the cam1104 of the hinge 1100 in a second open position. The section view 2400,for instance, corresponds to the cross-section 1704 illustrated in FIG.17.

The section view 2400 illustrates that when the kickstand 302 is in theposition 2300, the inner cam surface 1400 is not in contact with theinner follower surface 1602. As mentioned above, contact between the cam1104 and the cam follower 1106 in open positions after the open position2000 occurs between the outer cam surface 1402 and the outer followersurfaces 1604 (illustrated in other Figures), and not between the innercam surface 1400 and the inner follower surface 1602.

FIG. 25 illustrates a partial rear view 2500 of the computing device 102with the kickstand 302 in the position 2300. Further illustrated are thecam 1104 and the support plates 1108 a, 1108 b.

FIG. 26 illustrates the kickstand 302 in a position 2600. In at leastsome embodiments, the position 2600 corresponds to a third preset openposition for the kickstand 302, such as the position 800 illustratedwith reference to FIG. 8. The kickstand 302 is placed in the position2600, for instance, responsive to a user further opening the kickstand302 past the position 2300 introduced above. Further illustrated is apartial side section view 2602 of the computing device 102, includingthe kickstand 302 attached to the cam 1104 of the hinge 1100 in a thirdopen position. The section view 2602, for instance, corresponds to thecross-section 1702 illustrated in FIG. 17.

According to various implementations, movement of the kickstand 302 fromthe position 2300 to the position 2600 is initially resisted by pressurefrom the second follower catch 2306 against the first cam catch 2102.However, when movement of the first cam catch 2102 proceeds past anouter follower point 2604, pressure from the outer follower surface 1604against the first cam catch 2102 drives the cam 1104 to the position2600. In the position 2600, the first cam catch 2102 engages with theouter follower surface 1604.

For instance, if a user begins opening the kickstand 302 further pastthe position 2300 but releases the kickstand 302 before the first camcatch 2102 proceeds past the outer follower point 2604, the cam 1104 andthus the kickstand 302 will snap back into the position 2300. However,when movement of the kickstand 302 proceeds past the position 2300 suchthat the first cam catch 2102 proceeds past the outer follower point2604, the cam 1104 and thus the kickstand 302 will snap into theposition 2600. For example, consider that a user releases the kickstand302 when the first cam catch 2102 is past outer follower point 2604. Insuch a case, the sloped profile of the outer follower surface 1604 issuch that pressure from outer follower surface 1604 (provided by thehinge spring 1110) against the first cam catch 2102 drives the cam 1104and thus the kickstand 302 into the position 2600 independent of anexternally applied (e.g., user-applied) force.

For example, the hinge 1100 is constructed such that unless a specifiedthreshold force is applied to the kickstand 302, the hinge 1100 will notdisengage from the position 2600.

Further illustrated is that in moving from the position 2300 to theposition 2600, engagement of the second cam catch 2308 with the cam stop2310 causes the support plate 1108 to rotate with the cam 1104.Generally, movement of the support plates 1108 enables the hinge 1100 toprovide stability to the kickstand 302 when open to various openpositions.

FIG. 27 illustrates the kickstand 302 in the position 2600 introducedabove. Further illustrated is a partial side section view 2700 of thecomputing device 102, including the kickstand 302 attached to the cam1104 of the hinge 1100 in a third open position. The section view 2700,for instance, corresponds to the cross-section 1700 illustrated in FIG.17.

As illustrated here, in the position 2600 the support plate 1108partially protrudes from the hinge frame 1102. Movement of the supportplate 1108 to the position 2600, for instance, is based on the interfacebetween the plate guide 1204 of the hinge frame 1102 and the supportchannel 1306 of the support plate 1108. Further, a plate catch 2702 ofthe support plate 1108 engages with a follower contact 2704 of the camfollower 1106. According to various implementations, engagement of theplate catch 2702 with the follower contact 2704 prevents the supportplate 1108 from rotating toward a further open position unlesssufficient force is applied to the kickstand 302.

For instance, engagement of the plate catch 2702 with the followercontact 2704 enables the kickstand 302 to persist in the position 2600.Spring pressure from the hinge spring 1110, for example, holds outerfollower surface 1604 against the first cam catch 2102 and thus preventsthe cam 1104 and thus the kickstand 302 from disengaging from theposition 2600 unless sufficient external force is applied. Thus, absentforce directly and/or indirectly applied to the kickstand 302, the platecatch 2702 will not disengage from the follower contact 2704. Forexample, the hinge 1100 is constructed such that unless a specifiedthreshold force is applied to the kickstand 302, the hinge 1100 will notdisengage from the position 2600.

The position 2600, for instance, is considered a maximum open positionfor the kickstand 302 under normal operating conditions. A furtherillustrated below, movement of the hinge 1100 past the position 2600 ispossible but is considered to be an emergency escape option thatprevents damage to the kickstand 302 when excessive force is applied tothe kickstand.

FIG. 28 illustrates a partial rear view 2800 of the computing device 102with the kickstand 302 in the position 2600. The rear view 2800illustrates that in the position 2600, the support plates 1108 a, 1108 bpartially protrude from the hinge frame 1102. Further shown is theengagement between the second cam catch 2308 of the cam 1104 and camstop 2310 of the support plate 1108 a that enables movement of thesupport plates 1108 between various open positions.

FIG. 29 illustrates the kickstand 302 in a position 2900. The position2900, for instance, represents a 180 degree rotation of the kickstand302 from a fully closed position, e.g., from the position 1800 discussedabove. In at least some embodiments, the position 2900 corresponds to anemergency escape position that is provided to prevent damage to thekickstand 302 and/or other components. For instance, rotation of thekickstand 302 to a further open position past the position 2600discussed above (e.g., a third preset open position) is not consideredto be a normal operating condition. However, such rotation may occur,such as inadvertently in response to various events.

For example, consider that the computing device 102 is resting on atable or other surface with the kickstand in the position 2600. A usermay accidentally place an object such as a book on the computing device102, which exerts sufficient force on the kickstand 302 such that thekickstand 302 disengages from the position 2600 and rotates to theposition 2900. As further detailed below, the force required to causethe kickstand 302 to rotate from the position 2600 to the position 2900is significantly greater than the force required to transition betweenother open positions discussed above.

Further illustrated in FIG. 29 is a side view 2902 of the hinge 1100 inthe position 2900, including the hinge frame 1102, the cam 1104, the camfollower 1106, and the support plate 1108. In the position 2900, the cam1104 disengages from the cam follower 1106 and the support plate 1108remains engaged with the cam follower 1106 to enable the hinge 1100 tofunction as an integrated and interconnected mechanism even in anemergency escape scenario. As further discussed below, this enables auser to return the kickstand 302 to a functioning position (e.g., one ofthe preset open positions discussed above) with minimal effort. Forinstance, a user may apply force to the kickstand 302 in a direction2904 to return the kickstand 302 to one or more of the positionsdiscussed above.

When the hinge 1100 is in the position 2900, the support plate 1108compresses the cam follower 1108. For instance, a plate point 2906 ofthe support plate 1108 engages with a follower point 2908 of the camfollower 1106 and applies pressure to the cam follower 1106. Accordingto various implementations, compressing the cam follower 1106 preventsthe cam follower 1106 from engaging with the cam 1104 until thekickstand 302 is reset to a normal operating position.

FIG. 30 illustrates a side view 3000 of the hinge 1100 in the position2900, introduced above. The side view 3000 illustrates that in theposition 2900, the cam 1104 is engaged with the support plates 1108 a,1108 b via engagement of the cam channel 1404 with the cam guide 1302.Further, the support plates 1108 a, 1108 b are engaged with the hingeframe 1102 via engagement of the support channel 1306 with the plateguide 1204. This engagement of the cam 1104 with the support plates1108, and the support plates 1108 with the hinge frame 1102, enablescomponents of the hinge 1100 to remain interconnected in the position2900. Thus, even with the cam 1104 completely removed from the hingeframe 1102, the kickstand 302 remains connected to the computing device102 and can be returned to normal operating positions, such as thosediscussed above.

The side view 3000 further illustrates engagement of the second camcatch 2308 with the cam stop 2310, which as discussed above, pulls thesupport plates 1108 out of the hinge frame 1102 to various openpositions in response to user manipulation of the kickstand 302.

FIG. 31 illustrates a bottom view 3100 of the hinge 1100 in the position2900. The view 3100 illustrates engagement of the support plate 1108 bwith the hinge frame 1102 via engagement of the support channel 1306with the plate guide 1204. Further illustrated is engagement of thesecond cam catch 2308 of the cam 1104 with the cam stop 2310 of thesupport plate 1108 a.

FIG. 32 illustrates a partial view 3200 of the cam 1104 relative to thesupport plate 1108 a. The view 3200, for instance, represents a positionof the cam 1104 relative to the support plate 1108 a when the hinge 1100is in a closed position, e.g., the position 1800 discussed above.Included in the view 3200 are the first cam catch 2102, the second camcatch 2308, and the cam stop 2310.

FIG. 33 illustrates a partial view 3300 of the cam 1104 relative to thesupport plate 1108 a. The view 3300, for instance, represents a positionof the cam 1104 relative to the support plate 1108 a when the hinge 1100is in an open position, e.g., the position 2600 discussed above and/orothers of the open positions. Further illustrated is engagement betweenthe second cam catch 2308 and the cam stop 2310 of the support plate1108, which enables movement of the support plates 1108 in response tomovement of the cam 1104.

In at least some implementations, the contact surface of the cam stop2310 that engages with the second cam catch 2308 is angled inward towardthe second cam catch 2308, e.g., is not normal to the surface of thesupport plate 1108. Further, the opposing contact surface of the secondcam catch 2308 is angled to provide a flat contact face between the camstop 2310 and the second cam catch 2308. According to variousimplementations, this inward angling of the cam stop 2310 causes thesecond cam catch 2308 to pull the support plate 1108 inward and thusprovide for stability of the interconnected components of the hinge1100.

Having discussed some example kickstand and hinge positions andcomponents, consider now a discussion of an example responsivenessprofile associated with movement between the different positions.

Hinge Response Profile

Considering the different positions of the hinge 1100 and the kickstand302 discussed above, the response profile experienced during movement ofthe kickstand 302 between the different positions is influenced byvarious factors. For instance, pressure from the hinge spring 1110against the cam follower 1106 and thus the cam 1104 provides pressureagainst the various components. Depending on which position thecomponents are in, the pressure either resists or encourages movement ofthe components of the hinge 1100.

Further, interaction between the different surfaces of the cam 1104 andthe cam follower 1106 contributes to a responsiveness profile of thehinge 1100 and the kickstand 302. For instance, when the kickstand 302moves from the closed position 1800 to the first open position 2000,responsiveness of the hinge 1100 is determined by contact between theinner cam surface 1400 and the inner follower surface 1602. When thekickstand moves past the first open position 2000 to the positions 2300,2600, responsiveness of the hinge 1100 is determined by contact betweenthe outer cam surfaces 1402 a, 1402 b and the outer follower surfaces1604 b, 1604 a, respectively. Thus, a transition between guidingsurfaces occurs at the first open position 2000.

According to various implementations, opening of the hinge 1100 afterthe third open position 2600 is based on interaction between the supportplates 1108 and the cam follower 1106. For instance, torque required tomove the hinge 1100 to the position 2900 (e.g., the emergency escapeposition) is based on interaction between the support plates 1108 andthe cam follower 1106.

In at least some embodiments, responsiveness of the hinge 1100 can becharacterized via a torque profile that indicates various forces thatoccur during movement of the kickstand 302 between various positions.For instance, interaction between the different cam surfaces and thedifferent cam follower surfaces provides a detent mechanism that resultsin a tactile response profile for movement of the kickstand 302 betweendifferent preset positions. Consider, for example, the following exampletorque profiles.

FIG. 34 illustrates a torque graph 3400 that includes an opening torquecurve 3402 and a closing torque curve 3404. The torque graph 3400further includes an angle axis 3406 and a torque axis 3408. The angleaxis 3406 (e.g., the x-axis) indicates opening angle values for thekickstand 302 relative to an associated apparatus, e.g., the computingdevice 102. The torque axis 3408 (e.g., the y-axis) indicates differenttorque values for the torque graph 3400. In this particular example, thetorque values are indicated in Newton-millimeters (N-mm). This is not tobe interpreted as limiting, however, and torque values may be measuredin a variety of different units. Further, different forces may bemeasured to characterize the movement of the hinge 1100 and/or thekickstand 302.

According to one or more implementations, the opening torque curve 3402represents torque transferred from the kickstand 302 to the cam 1104when the kickstand is opened (e.g., via user manipulation) from a closedposition to various open positions. The closing torque curve 3404represents torque transferred from the kickstand 302 to the cam 1104when the kickstand is moved (e.g., via user manipulation) from variousopen positions towards a closed position.

As further detailed below, the different torque curves are associatedwith certain “action points” or “action regions” that demonstrate theoverall responsiveness profile of the hinge mechanisms discussed herein.The opening torque curve 3402, for instance, includes a first openingpeak 3410, a first opening threshold 3412, a second opening peak 3414, asecond opening threshold 3416, a third opening peak 3418, and a thirdopening threshold 3420. The closing torque curve 3404 includes, forexample, a first closing peak 3422, a first closing threshold 3424, asecond closing peak 3426, a second closing threshold 3428, a thirdclosing peak 3430, and a third closing threshold 3432. Exampleattributes of these different points/regions are now discussed.

As an example implementation, consider that the kickstand 302 is in aclosed position, e.g., 0 degrees on the torque graph 3400. A usermanipulates the kickstand 302 from the closed position towards an openposition. Following the opening torque curve 3402, torque againstopening of the kickstand 302 gradually increases until the openingtorque curve 3402 reaches the first opening peak 3410 at an openposition of about 23 degrees. After the first opening peak 3410, torquevalues rapidly decrease until the opening torque curve 3402 intersectsthe angle axis 3406 at the first opening threshold 3412. In thisparticular example, the first opening threshold 3412 represents an openposition of approximately 27 degrees.

According to one or more embodiments, if the kickstand 302 is releasedprior to reaching the third closing threshold 3432 (e.g., at less than23 degrees open), the kickstand will snap back to closed, e.g., 0degrees. Further, if the kickstand 302 is released after the firstopening threshold 3412, the kickstand 302 will snap to a first presetopen position, e.g., at 48 degrees. Thus, the first opening threshold3412 represents a threshold open position for the kickstand 302 thatwhen exceeded, allows the kickstand 302 to snap into a first preset openposition. The first preset open position, for instance, corresponds tothe position 2000 discussed above.

If the third closing threshold 3432 is not exceeded and the kickstand302 is released, the kickstand will snap back into a closed position.For instance, if a user releases the kickstand at an open angle lessthan the third closing threshold 3432, torque active on the cam 1104 ischaracterized by the closing torque curve 3404.

Consider now that a user further manipulates the kickstand from thefirst open position (e.g., at 48 degrees) towards a further openposition. Continuing from 48 degrees on the opening torque curve 2202,it can be seen that torque values rapidly increase to the second openingpeak 3414. In at least some embodiments, this increase in torquerepresents a threshold torque required to move the kickstand from afirst preset open position (e.g., the position 2000) to a second presetopen position, e.g., the position 2300. For instance, the second openingpeak 3414 represents the torque required to disengage the first camcatch 2102 from the first follower catch 2104, as illustrated above withreference to FIGS. 21 and 23. In this particular example, the thresholdtorque represented by the second opening peak 2214 is approximately 230N-mm.

If a user manipulates the kickstand 302 past the second opening peak3414, it can be seen that the torque values of the opening torque curve3402 rapidly decrease until the opening torque curve 3402 intersects theangle axis 3406 at the second opening threshold 3416. In this particularexample, the second opening threshold 3416 represents an open positionof approximately 65 degrees. According to one or more embodiments, ifthe kickstand 302 is released prior to reaching the second closingthreshold 3428 (e.g., between the first preset open position and thesecond closing threshold 3428), the kickstand will snap back to thefirst preset open position. If the kickstand 302 is released after thesecond opening threshold 3416, the kickstand 302 will snap to a secondpreset open position, e.g., at 84 degrees. Thus, the second openingthreshold 3416 represents a threshold open position that when exceeded,allows the kickstand 302 to snap into the second preset open position.In at least some embodiments, the second preset open position representsthe position 2300 discussed above.

Consider now that a user further manipulates the kickstand from thesecond open position (e.g., at 84 degrees) towards a further openposition. Continuing from 84 degrees on the opening torque curve 3402,it can be seen that torque values rapidly increase to a third openingpeak 3418. In at least some embodiments, this increase in torquerepresents a threshold torque required to move the kickstand from asecond preset open position (e.g., the position 2300) to a third presetopen position, e.g., the position 2600. For instance, the third openingpeak 3418 represents the torque required to disengage the first camcatch 2102 from the second follower catch 2306, as illustrated abovewith reference to FIGS. 23 and 26. In this particular example, thethreshold torque represented by the third opening peak 3418 isapproximately 300 N-mm.

If a user manipulates the kickstand 302 past the third opening peak3418, it can be seen that the torque values of the opening torque curve3402 rapidly decrease until the opening torque curve 3402 intersects theangle axis 3406 at the third opening threshold 3420. In this particularexample, the third opening threshold 3420 represents an open position ofapproximately 100 degrees. According to one or more implementations, ifthe kickstand 302 is released prior to reaching the first closingthreshold 3424 (e.g., between the second preset open position and thefirst closing threshold 3424), the kickstand will snap back into thesecond preset open position. If the kickstand 302 is released after thethird opening threshold 3420, the kickstand 302 will snap to a thirdpreset open position, e.g., at 118 degrees. Thus, the third openingthreshold 3420 represents a threshold open position that when exceeded,allows the kickstand 302 to snap into the third preset open position. Inat least some embodiments, the third preset open position represents theposition 2600 discussed above.

Continuing past the third preset open position at 118 degrees, it can beseen that the torque values rapidly increase past the previous openingtorque values. In at least some embodiments, this indicates that thekickstand 302 is not intended to be opened past the third preset openposition (e.g., 118 degrees) under normal operating scenarios. Forinstance, opening the kickstand past the third preset open position isbased on an emergency release scenario, such as discussed above withreference to FIGS. 29-31.

When closing the kickstand 302 from the open position 2600 and/or otheropen position, torque acting on the cam 1104 is characterized by theclosing torque curve 3404. Generally, the interpretation of the closingtorque curve 3404 is opposite that of the opening torque curve 3402since the direction of motion (e.g., closing vs. opening) is reversed.In at least some embodiments, for example, negative torque values on theclosing torque curve 3404 represent closing torque applied by the user,and positive torque values on the closing torque curve 3404 representthe tendency of the kickstand to snap into a position (e.g., an openposition or closed) absent resistance and/or force applied from a user.

For instance, consider that a user manipulates the kickstand 302 fromthe third preset open position of 118 degrees towards a closed position.Traversing the closing torque curve 3404 from the third preset openposition, it can be seen that the torque forces that occur when closingthe kickstand 302 are less than those that occur when opening thekickstand 302. This difference in torque profiles between opening toqueand closing torque is caused at least in part by the differing profilesof the different surfaces of the cam 1104 and the cam follower 1106.

As referenced above, the closing torque curve 3404 includes the firstclosing peak 3422, which represents a threshold torque force required tomove the kickstand 302 from the third preset open position to the secondopen position. When the kickstand is closed past the first closing peak3422, the closing torque resistance decreases until the closing torquecurve 3404 intersects the angle axis 3406 at the first closing threshold3424. In this particular example, the first closing threshold 3424represents an open angle of approximately 95 degrees. According to oneor more implementations, if a user releases the kickstand 302 betweenthe third preset open position and prior to reaching the third openingthreshold 3420, the kickstand 302 will snap back into the third presetopen position. However, if the user releases the kickstand 302 afterreaching the first closing threshold 3424 (e.g., at or less than about95 degrees), the kickstand 302 will snap into the second preset openposition.

The second closing peak 3426 represents a threshold torque required tomove the kickstand 302 from the second present open position to thefirst preset open position, e.g., to transition from the position 2300to the position 2000. When the kickstand is closed past the secondclosing peak 3426, the closing torque resistance decreases until theclosing torque curve 3404 intersects the angle axis 3406 at the secondclosing threshold 3428. In this particular example, the second closingthreshold 3428 represents an open angle of approximately 61 degrees.

In at least some embodiments, if a user releases the kickstand 302between the second preset open position and prior to reaching the secondopening threshold 3416, the kickstand 302 will snap back into the secondpreset open position. However, if the user releases the kickstand 302after reaching or exceeding the second closing threshold 3428 (e.g., ator less than about 61 degrees), the kickstand 302 will snap into thefirst preset open position.

The third closing peak 3430 represents a threshold torque required tomove the kickstand 302 from the first present open position to a closedposition, e.g., to transition from the position 2000 to the position1800. When the kickstand is closed past the second closing peak 3430,the closing torque resistance rapidly decreases until the closing torquecurve 3404 intersects the angle axis 3406 at the third closing threshold3432. In this particular example, the third closing threshold 3432represents an open angle of approximately 24 degrees.

In at least some embodiments, if a user releases the kickstand 302between the second preset open position and prior to reaching the firstopening threshold 3412, the kickstand 302 will snap back into the firstpreset open position. However, if the user releases the kickstand 302after reaching or exceeding the third closing threshold 3432 (e.g., ator less than about 24 degrees), the kickstand 302 will snap into theclosed position, e.g., 0 degrees.

As illustrated in FIG. 34, the spaces (e.g. differences) between theopening thresholds and the closing thresholds are minimized. Forinstance, the difference between the first opening threshold 3412 andthe third closing threshold 3432 is minimized. Further, the differencebetween the second opening threshold 3416 and the second closingthreshold 3428 is minimized. Still further, the difference between thethird opening threshold 3420 and the first closing threshold 3424 isminimized. This contributes to the “snappiness” of the kickstand whenmoved between different positions, and reduces the likelihood that thekickstand will stick in an unintended position, e.g., outside of one ofthe preset open positions.

As further illustrated by the torque graph 3400, the hinge mechanismdiscussed herein is designed to minimize the torque required to maintainthe “snappiness” response. In at least some embodiments, this minimumtorque is approximately 20 N-mm. Further, the opening torque curve 3402and the closing torque curve 3404 are trapezoidal in shape, for example,as opposed to sinusoidal curves. This illustrates the snappy transitionbetween the different preset hinge positions.

Thus, according to various implementations, the torque curvescharacterize torque values that apply during movement of the kickstand302. For instance, the opening torque curve 3402 represents the torquethat is applied when opening the kickstand 302 from the closed position1800 through the various different open positions. Further, the closingtorque curve 3404 represents the torque that is applied when closing thekickstand 302 from various open positions to the closed position 1800.

It should be noted that in the closing torque curve 3404, a negativetorque represents the user actively applying torque to close thekickstand, e.g., external force applied to the kickstand 302. A positivetorque on the closing torque curve 3404 represents the kickstand tendingto close itself due to force generated internally to the hinge 1100(e.g., by the hinge spring 1110) to cause the hinge to “snap” betweenvarious positions.

FIG. 35 illustrates a torque graph 3500 that represents different torqueforces that occur when the kickstand is opened to the position 2900,e.g., the emergency escape position discussed above. The torque graphincludes an opening torque curve 3502, a closing torque curve 3504, anangle axis 3506, and a torque axis 3508. Further illustrated are thepreset open positions discussed above.

The torque graph 3500 includes an emergency release peak 3510, whichcorresponds to an amount of torque required to disengage the kickstand302 from the third preset open position to a further open position,e.g., to open the kickstand 302 to the position 2900. As discussedabove, in at least some implementations the kickstand 302 is notintended to be opened past the third preset open position under normallyoperating conditions. Thus, the amount of torque required to furtheropen past the third preset open position is considerably greater thanthe torque values discussed with regard to the previous open positions.

In this particular example, the emergency release peak 3510 indicatesthat approximately 1700 N-mm are required to open the kickstand 302 pastthe third preset open position. For instance, the emergency release peak3510 specifies an amount of opening torque required on the kickstand 302to disengage the plate catch 2702 form the follower catch 2704,discussed above with reference to FIG. 27. Thus, exceeding the openingtorque specified by the emergency release peak 3510 while the kickstand302 is in third preset open position causes the kickstand to transitionto an emergency escape position, e.g., the position 2900.

Notice in the torque graph 3500 that the closing torque curve 3504differs from the closing torque curve 3404 discussed with reference toFIG. 34. The closing torque curve 3504 demonstrates that when thekickstand 302 is opened past the third preset open position to theemergency escape position, there is little resistance to resetting thehinge 1100 to a normal operating condition.

For instance, refer back to FIG. 29. As illustrated in FIG. 29, when thehinge 1100 is opened to the position 2900, the support plates 1108 holdthe cam follower 1106 in a compressed position within the hinge frame1102. When the kickstand 302 is closed from the position 2900, becausethe cam follower 1106 is compressed, the cam follower 1106 does notengage with the cam 1104 until the kickstand 302 pushes the supportplates 1108 to disengage the support plates 1108 from the cam follower1106. When the support plates 1108 disengage from the cam follower 1106,the hinge spring 1110 presses the cam follower 1106 to engage with thecam 1104, thus resetting the hinge 1100 to a normal operating condition.In at least some implementations, the hinge reset occurs at an openposition of 48 degrees, e.g., the first preset open position and/or theposition 2000.

Accordingly, embodiments discussed herein provide a stable hingemechanism that enables an attached component (e.g., a kickstand) to beadjusted between multiple preset positions. It is to be appreciated thatthe example device orientations, kickstand positions, hinge positions,hinge preset positions, torque values, and so forth discussed above arepresented for purposes of example only. Thus, a wide variety ofdifferent device orientations, kickstand positions, hinge positions,hinge preset positions, and torque values not specifically mentionedherein may be implemented within the spirit and scope of the claimedembodiments.

For instance, an attachment mechanism used to attach a kickstand to acomputing device (e.g., the hinge 1100 discussed above) can include anynumber and/or configuration of suitable preset stop positions to enablethe kickstand to be opened to a variety of different positions tosupport various orientations of a computing device. Further, examplehinges can be attached at any suitable position and/or portion of akickstand and/or computing device in accordance with the claimedembodiments.

In such acontext, processor-executable instructions may beelectronically-executable instructions.

The computer-readable storage media 3606 is illustrated as includingmemory/storage 3612. The memory/storage 3612 represents memory/storagecapacity associated with one or more computer-readable media.

Thememory/storage component 3612 may include fixed media (e.g., RAM, ROM, afixed hard drive, and so on) as well as removable media (e.g., Flashmemory, a removable hard drive, an optical disc, and so forth). Thecomputer-readable media 3606 may be configured in a variety of otherways as further described below.

Input/output interface(s) 3608 are representative of functionality toallow a user to enter commands and information to computing device 3602,and also allow information to be presented to the user and/or othercomponents or devices using various input/output devices.

Various techniques may be described herein in the general context ofsoftware, hardware elements, or program modules. Generally, such modulesinclude routines, programs, objects, elements, components, datastructures, and so forth that perform particular tasks or implementparticular abstract data types. The terms “module,” “functionality,” and“component” as used herein generally represent software, firmware,hardware, or a combination thereof. The features of the techniquesdescribed herein are platform-independent, meaning that the techniquesmay be implemented on a variety of commercial computing platforms havinga variety of processors.

An implementation of the described modules and techniques may be storedon or transmitted across some form of computer-readable media. Thecomputer-readable media may include a variety of media that may beaccessed by the computing device 3602. By way of example, and notlimitation, computer-readable media may include “computer-readablestorage media” and “computer-readable signal media.”

“Computer-readable storage media” may refer to media and/or devices thatenable persistent storage of information in contrast to mere signaltransmission, carrier waves, or signals per se. Thus, computer-readablestorage media refers to non-signal bearing media. The computer-readablestorage media includes hardware such as volatile and non-volatile,removable and non-removable media and/or storage devices implemented ina method or technology suitable for storage of information such ascomputer readable instructions, data structures, program modules, logicelements/circuits, or other data.

“Computer-readable signal media” may refer to a signal-bearing mediumthat is configured to transmit instructions to the hardware of thecomputing device 3602, such as via a network. Signal media typically mayembody computer readable instructions, data structures, program modules,or other data in a modulated data signal, such as carrier waves, datasignals, or other transport mechanism. Signal media also include anyinformation delivery media. The term “modulated data signal” means asignal that has one or more of its characteristics set or changed insuch a manner as to encode information in the signal. By way of example,and not limitation, communication media include wired media such as awired network or direct-wired connection, and wireless media such asacoustic, RF, infrared, and other wireless media.

As previously described, hardware elements 3610 and computer-readablemedia 3606 are representative of modules, programmable device logicand/or fixed device logic implemented in a hardware form that may beemployed in some embodiments to implement at least some aspects of thetechniques described herein, such as to perform one or moreinstructions. Hardware may include components of an integrated circuitor on-chip system, an application-specific integrated circuit (ASIC), afield-programmable gate array (FPGA), a complex programmable logicdevice (CPLD), and other implementations in silicon or other hardware.In this context, hardware may operate as a processing device thatperforms program tasks defined by instructions and/or logic embodied bythe hardware as well as a hardware utilized to store instructions forexecution, e.g., the computer-readable storage media describedpreviously.

Combinations of the foregoing may also be employed to implement varioustechniques described herein. Accordingly, software, hardware, orexecutable modules may be implemented as one or more instructions and/orlogic embodied on some form of computer-readable storage media and/or byone or more hardware elements 3610. The computing device 3602 may beconfigured to implement particular instructions and/or functionscorresponding to the software and/or hardware modules. Accordingly,implementation of a module that is executable by the computing device3602 as software may be achieved at least partially in hardware, e.g.,through use of computer-readable storage media and/or hardware elements3610 of the processing system 3604. The instructions and/or functionsmay be executable/operable by one or more articles of manufacture (forexample, one or more computing devices 3602 and/or processing systems3604) to implement techniques, modules, and examples described herein.
